I donīt think they will answer that question,sorry,
It might be possible to benchmark the harddrive with different fsb.
If thereīs no PCI lock the benches should be better with high fsb.
Also, if it is connected to the AGP it should be possible to see if anything happends when changing the AGP in Bios.
The only benchmark I have here right now is Sandra, wich sux

Could try it though.
